Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Intelbras IWR 3000N 1.9.8 exposes the Wi-Fi password in plaintext via the /api/wireless endpoint. Any unauthenticated user on the local network can directly obtain the Wi-Fi network password by querying this endpoint.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

How this class of weakness works · CWE-200

The application discloses data — error detail, internal paths, tokens, or other users' records — to someone who shouldn't see it. On its own it can look minor, but it hands attackers the map they need for a larger attack. Remediation is about minimising what's returned and enforcing authorization on every piece of data.

Upgrade available Upgrade to a release after 1.9.8
Recommended fix Moderate confidence

Latest available firmware version after 1.9.8 (check www.intelbras.com for the specific fixed release)

  1. 1. Check the official Intelbras support page (www.intelbras.com) for the latest firmware version for the IWR 3000N device
  2. 2. Download the firmware update from the official Intelbras website
  3. 3. Access the router's web administration interface
  4. 4. Navigate to the firmware update section (usually under Administration or System settings)
  5. 5. Upload and apply the new firmware version
  6. 6. After the update completes, verify the /api/wireless endpoint no longer exposes the Wi-Fi password in plaintext
  7. 7. Change the Wi-Fi password as a precautionary measure
